Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a separate air conditioner in which an indoor side and an outdoor side are separated.

Conventional structure and problems thereof Conventionally, the outdoor unit of this type of air conditioner has a heat exchanger, a fan, a fan motor, a compressor, etc. covered with an exterior to form a unit. Although this structure is easy to transport and install the outdoor unit, it may not be suitable for aesthetic reasons for the exterior of the house after installation or for occupying ground space.

Purpose of the Invention The present invention eliminates the drawbacks of the conventional air conditioners described above, and aims to maintain the aesthetic appearance of a house after installing an outdoor unit and to effectively utilize heat under the floor. .

Structure of the Invention In order to achieve this object, the present invention includes an opening that communicates with an opening provided in the fabric foundation of a house and an opening that communicates with the outside air, in the lower part of a cover that covers an outdoor heat exchanger. A shielding plate is provided to selectively shield one of the openings.

DESCRIPTION OF EMBODIMENTS The present invention will be described below with reference to the accompanying drawings showing one embodiment thereof.

In the figure, 1 is a cloth foundation for a house, on which a foundation 2 is fixed, an outer wall 3, a ceiling 4, and a floor 5.
A house is composed of: 6 indicates the outdoor ground, and 7 indicates the space under the floor of a house. Inside the room, an indoor unit 8 having a well-known structure is installed on the wall, and a compressor 9 is installed in the underfloor space 7. Outdoor heat exchanger 1 for radiating heat outdoors
0 is attached to the outer wall 3 by appropriate means such as metal fittings. Reference numeral 11 denotes a cover that covers the outdoor heat exchanger 10, the upper end of which is open toward the top, and the opening 14 of which extends close to the eaves 15. Further, inside the cover 11, an auxiliary fan 12 having outer airfoil-shaped blades and a motor 13 for driving the fan are installed, and furthermore, the cover 11
The lower part thereof has an opening 17 that communicates with an opening 16 formed in the cloth foundation 1, and an opening 18 that opens toward the outside. The shielding plate 19 provided at the lower part of the cover 11 performs a fan-shaped movement about the shaft 20 to close either the opening 17 or 18 mentioned above. That is, when the shielding plate 19 is tilted toward the opening 17 as shown by the solid line in FIG.
is opened, and when it is tilted toward the opening 18 as shown by the broken line, the opening 17 is opened.

Here, the indoor unit 8, compressor 9, and outdoor heat exchanger 10 are connected through refrigerant piping, forming a well-known refrigeration cycle.

In the above configuration, when the air conditioner performs cooling operation, the shielding plate 19 is connected to the opening 1 in contact with the outside.
8 is closed and an opening 17 is opened on the side that communicates with the underfloor. Further, the refrigerant that has absorbed heat in the indoor unit 8 is compressed by the compressor 9, and reaches the outdoor heat exchanger 10, where the heat is radiated. As mentioned above, the outdoor heat exchanger 10 is provided in the space between the outer wall 3 and the cover 11, and as the temperature of the outdoor heat exchanger 10 increases, the air in that space is heated and becomes an upward airflow, causing convection. This action cools the outdoor heat exchanger 10. Since the lower part of this cover 11 is connected to the opening 16 of the cloth foundation 1, cooling air is introduced from under the floor. Further, if the opening area of the opening 16 is insufficient, the auxiliary fan 12 is used to make up for the insufficiency in order to assist upward flow due to convection.

Therefore, for cooling the outdoor heat exchanger 10, the air under the floor, which is lower than the outside air, is effectively used, which is efficient. In addition, a compressor 9 installed in the underfloor space 7
is covered with a soundproofing material 21 to prevent noise, and the whole is surrounded by a box 22, so the soundproofing effect is also great. Furthermore, since the tip of the cover 11 is open near the eaves 15, rainwater does not enter.

On the other hand, in the case of heating operation, the shielding plate 19 closes the opening 17 communicating with the underfloor, and leaves the opening 18 in contact with the outside open. Therefore, the refrigerant condensed in the indoor unit 8 evaporates in the outdoor heat exchanger 10 and absorbs the heat of the outside air entering through the opening 18. The air is then compressed by the compressor 9, and the heat is radiated by the indoor unit 8 to provide a heating effect. The auxiliary fan 12 during heating operation is operated continuously.

Effects of the Invention As is clear from the above embodiments, the air conditioner of the present invention has a compressor that constitutes a refrigeration cycle installed under the floor of a house, and an outdoor heat exchanger that constitutes the refrigeration cycle together with the compressor. , installed on the exterior wall of the house, the outdoor heat exchanger is cooled by the air under the floor during cooling operation, and exchanges heat with the outside air during heating operation, so that the heat exchanger is generated from the outdoor heat exchanger during cooling operation. The outdoor heat exchanger can be cooled using the air under the floor, which has a lower temperature than the outside air, by using the rising airflow of warm air generated by the heat generated. Since it uses convection, the blower only needs to be operated as an auxiliary device, and it is small and consumes little power, making it highly effective in saving energy. Also, during heating operation, heat is absorbed from outside air directly through the outdoor heat exchanger, improving heat exchange efficiency. Furthermore, since the compressor is installed under the floor and the outdoor heat exchanger is attached to the outside wall of the house, wasted space is effectively used, the installation footprint is extremely small, and the vibration and noise of the compressor are soundproofed. It has various advantages, such as less air being transmitted to the outside due to the box body equipped with the material, and quiet air conditioning.
